Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47920, here are decompositions:
- 3 + 47917 = 47920
- 17 + 47903 = 47920
- 83 + 47837 = 47920
- 101 + 47819 = 47920
- 113 + 47807 = 47920
- 179 + 47741 = 47920
- 239 + 47681 = 47920
- 263 + 47657 = 47920
Showing the first eight; more decompositions exist.
